UNITED STATES PATENT GEEIGE GEORGE B. MARKLE, OF HAZLETON, PENNSYLVANIA.

IMPROVEMENT IN SEPARATRS FOR ORE AND COAL.

Specification forming part of Letters Patent No. 148,727, dated March 17, 1574; application filed 4 March 5, 1874.

To all whom it may concern:

Be it known that I, G. B. MARKLE, of Hazleton, in the county of Luzerne and State of Pennsylvania, have invented a new and Improved Coal and Ore Separator, of which the following :is a speciiication:

The object of1 my invention is to rapidly scparate coal from slate, but it may be used for separating substances of different speciiic gravities.

Figure lis a longitudinal vertical section on line Fig. 2 is a p lan view of the machille.

The invention consists in the lconstruction of a machine that may be placed directly in the coal-chute, or in the saine line with it, and in the peculiar mechanism of the several parts.

Ais the box or chute. H is the tank. D D are the eccentrics, and C the connectingrods. G is a gate or opening attached to the tank H. B is the opening at the end of the jig or chute. F is the endless belt or carrier. E is the lever-arm for regulating the opening B. K K are the trunnions for sustaining the stationary end of the box or chute A. The machine is operated by the gear-wheels and bands, as plainly shown in Fig. l of the drawing.

The operation of the machine is as follows: A vibrating motion is given to the box or chute A by the eccentrics D and connecting rods C. The coal, slate, or other substances enter the chute A, pass over the bars through the water, and, by the effect of the swinging motion, the coal or lighter substances are thrown out over the dam G into a chute or other receptacle, while the slate or heavier substances gravitate through the opening B, at' the end oi' the box or chute A, and are then carried up and thrown out by the endless belt or carrier F. The opening B is regulated by the gate or dam G and lever-arm E.

It will be observed that the slotted bottom of the separator is sectional-shaped, and that the bars are longitudinal and oval.

Having described my invention, I claiml. The box or chute A, constructed in sec-- tions, with longitudinal and ovalshaped bars, one end resting in the trunnions K, suspended at the other to the arms C, and vibrated by the eccentrics D, all constructed as described, and for the purposes set forth.

2. The gate G, as attached to the tank H, and operated by the leverar1n E.

3. The endless belt or carrier F in the tank H, constructed as described, for the purposes set forth.

4.. The combination of the chute A, constructed and operated as shown, the gate G, the endless belt, and'tank H, arranged as represented and described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto subscribed my name in the presence of two witnesses.
